Understanding Health Anxiety

By Luna Fejza, RN, Certified Nurse Psychotherapist, Auren Wellness

A new pain appears. Your heart skips a beat. You feel dizzy, unusually tired, or notice something on your skin that you have not seen before.

Within minutes, your mind is searching for an explanation. You may search online, ask for reassurance, or book an appointment. You feel better for a while, but then the doubt returns: What if something was missed? What if it gets worse? What if this time it's serious?

Health anxiety is exhausting because the fear involves something genuinely important: your health. The goal is not to ignore your body or assume every symptom is caused by anxiety. It is to learn how to respond thoughtfully without allowing uncertainty to take over.

As both a Registered Nurse and Psychotherapist, I understand why simple reassurance often falls flat. People with health anxiety do not need to be told that they are imagining everything. They need help separating appropriate medical attention from patterns that keep anxiety going.

Quick answer: Health anxiety is an ongoing fear that physical sensations or symptoms may indicate a serious illness. It can lead to body checking, online searching, reassurance-seeking, frequent appointments, or healthcare avoidance. Treatment, particularly CBT, can help you respond more realistically to symptoms, reduce compulsive checking, and become more comfortable with health-related uncertainty.

What does health anxiety look like?

Everyone worries about their health occasionally. A new or concerning symptom may reasonably deserve medical attention. Health anxiety becomes a problem when the fear takes up a significant amount of time, interferes with daily life, or remains intense even after appropriate assessment.

It may look like:

• Searching symptoms online and becoming increasingly frightened by the results
• Frequently asking family members or healthcare professionals for reassurance
• Worrying that normal test results may be inaccurate or that something was overlooked
• Avoiding appointments, tests, hospitals, or health information because the possibility of bad news feels unbearable

Why reassurance rarely lasts

You notice a sensation and interpret it as dangerous. Anxiety rises, so you check, search online, or seek reassurance. When nothing serious is found, your anxiety settles.

The problem is that your brain may learn the wrong lesson. Instead of learning, I noticed something uncertain and was able to cope, it learns, I was safe only because I checked.

Internet searching can intensify this cycle. Search results include common explanations and frightening possibilities, but anxiety focuses on the worst-case scenario. A mild symptom can quickly feel like evidence of a rare disease simply because that explanation feels most threatening.

This does not mean you should never seek medical advice. It means that once a concern has been appropriately evaluated, repeatedly reopening the question may increase anxiety rather than provide lasting certainty.

The difficult balance between anxiety and medical care

I would never want someone to dismiss a new, severe, worsening, or otherwise concerning symptom simply because they have anxiety. Physical symptoms deserve appropriate assessment, and anxiety does not make them automatically insignificant.

At the same time, healthcare cannot offer complete certainty. Tests have limits, bodies produce sensations, and not every change requires investigation.

Health anxiety often demands a level of certainty medicine cannot provide: Prove that nothing is wrong now, that nothing was missed, and that nothing will happen later.

Therapy helps you move toward a more workable question: Based on the information I have, what is a reasonable response right now?

If health worries are taking up hours of your day or repeatedly sending you back into the same cycle, health anxiety therapy can help you develop a clearer and more balanced way of deciding when to act and when to step back.

How therapy can help with health anxiety

Cognitive behavioural therapy (CBT) has strong research support for health anxiety. A systematic review of 19 randomized trials found moderate-to-large improvements, with benefits often continuing after treatment ended.

Therapy may involve:

• Identifying catastrophic interpretations of physical sensations
• Setting healthier boundaries around online symptom searches
• Learning to tolerate uncertainty without assuming the worst
• Gradually approaching situations or information you have been avoiding

More recent evidence also supports approaches that incorporate exposure, acceptance, mindfulness, and metacognitive strategies. Treatment should be tailored to the individual.

Therapy is not about persuading you that you will never become ill. No therapist or healthcare professional can promise that. It is about helping you live without treating every sensation as an emergency and every uncertain possibility as an immediate threat.

When should you consider support?

Consider therapy when health worries repeatedly interrupt your day, strain relationships, drive excessive checking or avoidance, or persist despite appropriate medical reassurance.

You do not have to choose between taking your health seriously and treating anxiety. Good care makes room for both.
